Issue enabling HDRI for ImageMagick

I am installing ImageMagick on my server and upon entering the following config command:

    ./configure --enable-hdri

I get an output for the configuration that shows:

    --enable-hdri=yes       yes

But, when I try:

    identify -version

Am am given:

    Version: ImageMagick 6.6.0-4 2010-11-16 Q16 http://www.imagemagick.org
    Copyright: Copyright (C) 1999-2010 ImageMagick Studio LLC
    Features: OpenMP

With HDRI missing from the Features section.

Anyone know what gives? Thanks!

You should run

which identify

to see where your called identify binary is located:

• Is this really the one you have compiled and installed?
• Or is it rather another one (which pre-dates your own build and which wasn't cleanly removed)?
• You may be able to 'fix' this by tweaking your $PATH variable, or by calling the identify you really want with its full path...
